The Hanna HI782 High Range Nitrate Reagents provide a simple and reliable way to continue testing nitrate levels in your saltwater aquarium. This replacement pack is designed exclusively for use with the HI782 High Range Nitrate Checker Colorimeter. These reagents utilize a colorimetric method where a reaction with nitrate in your seawater sample produces a distinct color, allowing the checker to provide a precise digital reading and eliminating the guesswork of traditional color-matching test kits.

Each reagent pack contains enough pre-measured, high-purity chemicals to perform 25 high-range nitrate tests. Manufactured in a state-of-the-art facility, every packet is clearly marked with an expiration date and lot number, ensuring traceability and optimal performance. The pre-portioned packets guarantee ease of use, reduce the chance of error, and deliver consistent, accurate results every time you test your water parameters.

This reagent set is essential for any marine aquarist who already owns the Hanna HI782 Checker and needs to replenish their testing supplies. It is particularly useful for those maintaining fish-only systems or tanks with higher nutrient loads where nitrate levels may exceed the capacity of low-range test kits. Consistent monitoring with these reagents is key to managing water quality, controlling nuisance algae, and ensuring a stable environment for your aquatic life.
